The rules of spelling in English are the guiding principles that govern how words are written and spelled correctly. These rules provide a framework for consistency and clarity in written communication, enabling effective expression and comprehension. In English language, especially has words that are spelled nothing like they are pronounced. There are also many phonetically similar sounds which can take different spellings. So, Knowing spelling rules is the only way to learn it.
